No activities during the last year. The US (ANSI) PL/I group has just recommended that NCTIS and ANSI process the underlying document, ANS X3.53-1976, reaffirmed 1993, for reaffirmation for an additional five years. Project 97.22.6: ISO 6522 "General Purpose PL/I" No requests for clarifications or extensions in the last year. Consistent with the SC22 confirmation of this document in 1996, the US PL/I committee has just recommended that NCTIS and ANSI process the parallel and textually identical national document, ANS X3.74-1987, reaffirmed 1993, for reaffirmation for an additional five years. The reasons for this exactly parallel the recommendation made to SC22 in 1996: the language it defines is still in active use in many locations and that the availability of the Standard continues to be of use in procurements and in assessing conformance and interoperability. Other Issues While the internal format for storing dates is strictly implementation dependent and most known implementations do not have formats that would interact with Y2K issues, IS 6160 provides a "DATE" function that returns a two-digit year, with all the vunerabilities that implies. A replacement DATETIME function was introduced into IS 6522 for the explicit purpose of providing a mechanism that would not be Y2K-sensitive (see Annex B), but no action was ever taken to explicitly deprecate DATE. If there is a choice for any new development, IS 6522 continues to represent better practice than IS 6160 for this and other reasons. Otherwise, there are no significant outstanding issues affecting the PL/I standards. We remain interested in the future of other standards defined using formal or semi-formal methods, as we have concluded that these are not consistent with easy or rapid revisions or updates.
